Description
FEATURES
- Unique electrode shape maximizes the power created by the spark plug - Diamond Fire technology
- Electrode is a combination of performance and technology that results in an improved flame kernel shape
- This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
- The result is more complete combustion and an improvement in engine performance
- A truly premium performance plug

Vehicle Information
Honda Nighthawk 650 Motorcycle - Street (1982-1985)
The Honda Nighthawk 650, officially known as the CB650SC Nighthawk, was a popular standard motorcycle produced from 1982 to 1985. Designed for the American market, this model offered a blend of performance and reliability. Initially featuring an air/oil-cooled SOHC inline-four engine, it underwent a significant transformation during its production run, evolving to meet rider demands with enhanced technology and comfort. A major overhaul occurred in 1983. The 1982 model was powered by a 626cc SOHC engine with a 5-speed gearbox and chain final drive. From 1983 to 1985, the Nighthawk 650 received an all-new 656cc DOHC 16-valve engine, significantly boosting horsepower. This updated model also featured a 6-speed transmission and switched from a chain to a low-maintenance shaft drive system, along with hydraulic valve lash adjusters and a hydraulic clutch. Minor updates followed in 1984-1985, including cosmetic changes and exhaust revisions. No distinct trim levels were offered; instead, the model received yearly enhancements.
